A kind of spring shell fragment on and off switch
Technical field
This utility model relates to spring technology, particularly to a kind of spring shell fragment on and off switch.
Background technology
Spring is a kind of machine components utilizing elasticity to carry out work.General spring steel is made.Utilize its bullet
Property can control parts motion, relax impact or vibrations, stored energy, the size etc. of measurement power.Extensively
In machine, instrument.The stress of spring and deformation meet Hooke's law, i.e. stress just need to become with deformation quantity
Ratio.
On and off switch is people's one of indispensable parts when making electrical appliance, but, touching of prior art
Switch in use also exists wretched insufficiency: one is to press the button the non-homing that is stuck, and is in long-time
Conducting state, because its life-time service causes casing deformation, dirt is many, and spring is unable to be caused;Two is to contact not
Good, be in cannot conducting state, because its life-time service causes internal heavy wear to cause.Asking of this two aspect
Topic, causes computer cannot to start or close, and has had a strong impact on normal work and the life of people.The present invention
Internal employing triode device, mechanical device, it is not required to shell, completely solves existing Micro-touch switch and exist
Problem.

Lower section and with bearing Joint, described depression bar lower end is provided with pressing plate, between described bearing and power socket
It is provided with spring.
As preferably, described pin is provided with two, is conducive to connecting positive and negative polarities, it is to avoid send out when energising
The situations such as raw short circuit.
As preferably, being provided with chute in described power socket, beneficially button moves in power socket, it is to avoid
There is stuck situation with power socket in button.
As preferably, described power socket and button are all provided with projection, are provided by projection, it is possible to avoid
Button is ejected outside power socket by spring.
As preferably, bottom described pressing plate, it is set to semicircle indent, is conducive to and semicircle shell fragment tabling,
Elastic sheet switch can be protected during button, extend the service life of shell fragment.
The beneficial effects of the utility model are: owing to being provided with fixing seat, are conducive to power socket is fixed on wall
Wall or machine surface, owing to being provided with pin, be conducive to being energized elastic sheet switch, owing to being provided with
Elastic sheet switch, is conducive to carrying out power-off or energising, owing to arranging insulation spacer, desirably prevents so to make
Situation about getting an electric shock with appearance during on and off switch, owing to being provided with depression bar, is conducive to being opened by depression bar extrusion elastic
Pass carries out being energized or power-off, owing to being provided with spring, and can be extensive after using spring can make 2 times pressures of button
Restore the position of coming.

Detailed description of the invention
Refering to shown in Fig. 1 Fig. 2, a kind of spring shell fragment on and off switch, including power socket 1 and button 2, institute
Stating button 2 and be positioned at the top of power socket 1, described power socket 1 includes that fixing seat 3, pin 4 and shell fragment are opened
Closing 5, described fixing seat 3 is positioned at the both sides of power socket 1 and fixes with power socket 1, described pin 4
Being provided with more than one, described pin 4 is positioned at the bottom of power socket 1 and fixes with power socket 1, institute
Stating elastic sheet switch 5 and be positioned at the inside of power socket 1, described elastic sheet switch 5 is connected with pin 4, described shell fragment
Being provided with semicircle shell fragment 6 on switch 5, described button 2 includes bearing 7 and depression bar 9, described bearing 7 table
Face is provided with insulation spacer 8, and described insulation spacer 8 is fixed with bearing 7 tabling, and described depression bar 9 is positioned at
The lower section of bearing 7 and with bearing 7 Joint, described depression bar 9 lower end is provided with pressing plate 10, described bearing
Spring 11 it is provided with between 7 and power socket 1.
Described pin 4 is provided with two, is conducive to connecting positive and negative polarities, it is to avoid be short-circuited when energising
Situation.
Being provided with chute in described power socket 1, beneficially button 2 moves in power socket 1, it is to avoid button
2 there is stuck situation with power socket 1.
Described power socket 1 is all provided with projection with button 2, is provided by projection, it is possible to avoid spring 11
Button 2 is ejected outside power socket 1.
It is set to semicircle indent bottom described pressing plate 10, is conducive to and semicircle shell fragment 6 tabling, at button
Time can protect elastic sheet switch, extend the service life of shell fragment.
Novel a kind of spring shell fragment on and off switch of the present utility model in use, is pressed for 2 times by button,
In power socket 1, activity downwards, is then pressed elastic sheet switch 6 by depression bar 9, is energized, finally exists
During closedown, carry out power-off being pressed by button 2.
The beneficial effects of the utility model are: owing to being provided with fixing seat, are conducive to power socket is fixed on wall
Wall or machine surface, owing to being provided with pin, be conducive to being energized elastic sheet switch, owing to being provided with
Elastic sheet switch, is conducive to carrying out power-off or energising, owing to arranging insulation spacer, desirably prevents so to make
Situation about getting an electric shock with appearance during on and off switch, owing to being provided with depression bar, is conducive to being opened by depression bar extrusion elastic
Pass carries out being energized or power-off, owing to being provided with spring, and can be extensive after using spring can make 2 times pressures of button
Restore the position of coming.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is also
It is not limited to this, any change expected without creative work or replacement, all should contain in this practicality new
